Abstract
The charging/discharging protection circuit comprises a power supply end, a grounding end, and an under-voltage protection threshold control end; the power supply end is connected to a positive electrode of a battery; the grounding end is connected to a negative electrode of the battery; the under-voltage protection threshold control end is configured to receive a first control signal. The charging/discharging protection circuit is configured to reduce an under-voltage protection threshold of the battery under the control of the first control signal when the temperature of the battery is smaller than a set temperature threshold and the discharging current of the battery is greater than a set current threshold.
